Hi, I came home and all printer lights blinking. Unplugged for an hour, plugged, then it happened again. The help article on hp.com has a lot of light blinking colors and codes but not this. My WiFi is working; other devices on network working normally.

Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
- Did this happen after a recent window or software update?
- Did you make any changes to your printer?
While you respond to that, let's try these steps:
- With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
- Remove USB cable, if present.
- Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
- Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
- Turn on the printer and wait till the warm-up period finishes and the printer is idle.
Hope this helps! Keep me posted for further assistance.
